Description

Block chain-based evidence-based processing method and device and storage medium

Technical Field

The invention relates to the field of block chains, in particular to a block chain-based evidence-based method and device for processing a certificate and a storage medium.

Background

At present, the public link bottom layer architecture has a consensus mechanism, and has different emphasis on speed, safety and centralization degree and suitable scenes. The existing block chain consensus mechanism is mainly a mixed consensus on a chain of a single application scene, does not relate to a mechanism for achieving consensus on the chain of a plurality of application scenes, and still cannot well fit a real production scene. But the production activities of the real society are completed by multi-scenario cooperation, such as: the application scenes of a certain main chain are the game field, the sales field, the financial field and the like. At this time, the consensus mechanism applied to the main chain in the game field is more biased to the transaction speed between game users; the consensus mechanism applied to the main chain of the sales field is more biased to the security of the transaction between the customers; the consensus mechanism applied to the main chain in the financial field is more biased towards the centralization degree. Therefore, in the existing blockchain technology, due to different application scenarios and different emphasis on consensus mechanisms, when a transaction is performed between two or more users with different application scenarios, the consensus mechanism on the blockchain main chain cannot simultaneously meet the requirements of the users with multiple application scenarios. Therefore, in order to make the block chain technology better fit and serve the real world, it is important to form a new consensus for the block chains applied to a plurality of different scenes under different consensus conditions.

In view of the above-mentioned problem that the consensus mechanism on the main chain of the blockchain cannot simultaneously meet the requirements of users in multiple application scenarios when a transaction is performed between two or more users in different application scenarios due to different application scenarios and different emphasis on the consensus mechanism in the existing blockchain technology, no effective solution has been proposed at present.

The method provided by the first embodiment of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Fig. 1 shows a hardware configuration block diagram of a computer terminal (or mobile device) for implementing a block chain-based passcertificate processing method. As shown in fig. 1, the computer terminal 10 (or mobile device 10) may include one or more (shown as 102a, 102b, … …, 102 n) processors 102 (the processors 102 may include, but are not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA, etc.), a memory 104 for storing data, and a transmission device 106 for communication functions. Besides, the method can also comprise the following steps: a display, an input/output interface (I/O interface), a Universal Serial Bus (USB) port (which may be included as one of the ports of the I/O interface), a network interface, a power source, and/or a camera. It will be understood by those skilled in the art that the structure shown in fig. 1 is only an illustration and is not intended to limit the structure of the electronic device. For example, the computer terminal 10 may also include more or fewer components than shown in FIG. 1, or have a different configuration than shown in FIG. 1.

It should be noted that the one or more processors 102 and/or other data processing circuitry described above may be referred to generally herein as "data processing circuitry". The data processing circuitry may be embodied in whole or in part in software, hardware, firmware, or any combination thereof. Further, the data processing circuit may be a single stand-alone processing module, or incorporated in whole or in part into any of the other elements in the computer terminal 10 (or mobile device). As referred to in the embodiments of the application, the data processing circuit acts as a processor control (e.g. selection of a variable resistance termination path connected to the interface).

The memory 104 may be used to store software programs and modules of application software, such as program instructions/data storage devices corresponding to the block chain based general evidence processing method in the embodiment of the present invention, and the processor 102 executes various functional applications and data processing by running the software programs and modules stored in the memory 104, that is, implementing the block chain based general evidence processing method described above.

The display may be, for example, a touch screen type Liquid Crystal Display (LCD) that may enable a user to interact with a user interface of the computer terminal 10 (or mobile device).

Further, fig. 2 shows a system diagram according to an aspect of the present embodiment. The server 130 runs a blockchain, wherein the blockchain includes a main chain 131 and four side chains disposed on the main chain 131, where the four side chains are: side chain 1311, side chain 1312, side chain 1313, and side chain 1314. The server then applies blockchain backbone 131 to each of the different scenarios, for example: server 130 applies blockchain backbone 131 to scene 141, scene 142, scene 143, and scene 144, respectively. At this time, the user 101 in the scene 141, the user 102 in the scene 142, the user 103 in the scene 143, and the user 104 in the scene 144, which are different from each other, may freely combine the choices to perform the transaction activities on the main chain 131 through the main chain evidence of the block chain. Such as but not limited to: the user 101 in the scenario 141 wants to perform a transaction activity on the main chain 131 with the user 102 in the scenario 142. Since the user 101 and the user 102 are in different application scenarios, the consensus mechanism of the blockchain main chain 131 is emphasized. For example: scene 141 is a game system and scene 142 is an online shopping platform. At this time, the consensus mechanism of the blockchain main chain 131 running in the scenario 141 in terms of the transaction is more focused on the transaction speed, and the consensus mechanism of the blockchain main chain 131 running in the scenario 142 in terms of the transaction is more focused on the transaction security. Therefore, in order to satisfy the transaction requirements of the user 101 and the user 102 at the same time, the transaction activity is not only fast, but also has high security. The server 130 transfers the transaction activity occurring on the main chain 131 to the

side chain

1311, 1312, 1313 or 1314 for transaction. The server 130 utilizes a single application scenario of the side chain, and a common recognition mechanism of the side chain is not emphasized in the aspect of transaction, that is, the server has the advantages of high transaction speed and high security, thereby achieving the purpose of meeting the transaction requirements of the user 101 and the user 102 at the same time.

In the above operating environment, the first aspect of the present disclosure provides a block chain-based evidence-passing processing method as shown in fig. 3. Fig. 3 is a flowchart of a block chain-based general evidence processing method according to an embodiment of the present invention. The method may operate on the server 130 shown in fig. 2, and with reference to fig. 3, the method comprises:

s301: receiving an issuing request for issuing a first side chain pass certificate to a first account from a first terminal device, wherein the first side chain pass certificate is used for transaction on a side chain, and the first account is an account of the first terminal device on the side chain;

s302: obtaining first attestation information in response to the issuance request, wherein the first attestation information is for attesting that a first backbone credential corresponding to the first side chain credential is locked on the backbone;

s303: generating a first side link certificate on the side chain according to the first certificate information; and

s304: and sending the generated first side link certificate to a first account.

As described in the background art, in the conventional blockchain technology, due to different application scenarios and different priorities of consensus mechanisms, when a transaction is performed between two or more users with different application scenarios, the consensus mechanism on the blockchain main chain cannot simultaneously meet the requirements of the users with multiple application scenarios.

In order to solve the technical problem, the application provides a block chain-based evidence-based general processing method. For example, the method may receive, from first terminal device 141 through server 130, an issue request to issue a first side chain pass to a first account (i.e., the account of user 101 on blockchain side chain 1311). Server 130 then obtains, in response to the issuance request, first attestation information that attests that user 101 has locked his/her backbone credentials in an account on blockchain backbone 131. The server 130 then generates a first side-chain credential on the side chain 1311 based on the first credential information. Finally, the server 130 sends the generated first side link certificate to the first account.

Therefore, the block chain side chain 1311 has a single application scene, and the problem that a common recognition mechanism of the side chain in the aspect of transaction is emphasized does not exist, so that the requirements of users in different scenes for performing transaction activities based on the block chain can be met at the same time.

In this way, the server 130 of the present disclosure transfers the transaction activities on the main chain 131 between users in different application scenarios to the

side chains

1311, 1312, 1313, or 1314, so that the transaction activities on the side chains have the characteristics of high speed and high security. Therefore, the transaction requirements among users in a plurality of application scenes can be met simultaneously. Further, the problem that the consensus mechanism on the main chain of the blockchain cannot simultaneously meet the requirements of users in multiple application scenes when transaction activities are carried out between two or more users in different application scenes due to different application scenes and different emphasis of the consensus mechanism in the conventional blockchain technology is solved.

Optionally, the first certification information is certification information of the first terminal device for transferring the first main chain general certificate to a third account specified on the main chain. For example: the user 101 needs to transfer the main chain pass certificate in the account on the main chain 131 to a third account designated on the main chain, and the third account has a function of locking all the main chain pass certificates transferred to the account. After the user 101 transfers the backbone pass (e.g., 100 backbone passes) to the third account, the server 130 will issue the corresponding (e.g., 100) side passes to the account of the user 101 on the side chain. In this way, the number of free main chain passes that the user 101 possesses before locking the main chain pass (i.e., the unlocked main chain pass) is made equal to the sum of the number of free main chain passes that the user possesses after locking and the number of side chain passes. Therefore, a balance is achieved between the certificate passing locking and the certificate passing issuing, and the stability of the transaction activity based on the block chain system is further guaranteed.

Optionally, the third account includes a plurality of first verifiers, and the first attestation information is generated by the plurality of first verifiers confirming receipt of the first backbone attestation by the third account.

Specifically, the third account is commonly supervised and managed by a plurality of verifiers. For example: when the server 130 detects that the third account receives the main chain pass certificate transferred by the user 101, the server 130 sends the transferred transaction to the terminal devices of a plurality of verifiers respectively, and the plurality of verifiers verify the validity of the transferred transaction through digital signatures. When the server 130 receives the digital signatures of multiple verifiers, it generates the first certification information for certifying that the transaction is present and legitimate. By the method, before the server 130 issues the side chain voucher to the user 101, the proof that the main chain voucher is transferred to the third account by the user 101 is called, and then the side chain voucher is issued to the user 101 according to the proof, so that the issue of each side chain voucher is based on the evidence, and the stability of the transaction activity based on the block chain system is further ensured.

Optionally, the method further comprises: receiving a conversion request for converting a second side link pass certificate into a corresponding second main chain pass certificate from the first terminal equipment, wherein the second side link pass certificate is a side chain pass certificate sent to the first account by a fourth account of the second terminal equipment on a side chain; transferring the second side link certificate to a fifth account designated on the side link in response to the conversion request; acquiring a second main chain pass certificate corresponding to a second side chain pass certificate from a third account, wherein the second main chain pass certificate is a main chain pass certificate sent to the third account by a sixth account of the second terminal on the main chain; and sending the acquired second main chain certificate to the first account of the first terminal equipment.

Specifically, in the case where the user 101 of the first terminal device 111 wants to convert the second side link pass (100 side link passes) into the main link pass, where the second side link pass is obtained by the user 101 of the first terminal device 111 in a transaction with the user 102 of the second terminal device 112, issued by the server 130 to the account of the user 102 on the side link, the request that the user 101 convert the 100 side link passes into 100 main link passes through the terminal device 111 is sent to the server 130. The server 130 receives the conversion request, and then the server 130 transfers the 100 side certificates owned by the user 101 to the designated fifth account in response to the conversion request. And then obtains 100 main chain certificates transferred into the third account by the second terminal device 112. Finally, the server 130 sends the 100 main-chain passes to the first account of the first terminal 111 on the main chain. In this way, when the user 101 wants to convert the side-chain pass certificate of the user 102 obtained through the transaction into the main-chain pass certificate of the user 102, the server unlocks the main-chain pass certificate of the user 102, which is originally locked by transferring the user 102 into the third account, by transferring the side-chain pass certificate of the user 102 obtained by the user 101 into the fifth account, and sends the main-chain pass certificate of the user 102 after unlocking to the first account of the user 101 on the main chain.

In addition, according to the above scheme, referring to fig. 5, the transaction flow based on the chain transfer between the main chain and the side chain is roughly as follows: 1) the server 130 transfers the first main chain general certificate of the first account of the user 101 on the main chain 131 to a third account for locking; 2) the server 130 sends the transaction that the user 101 transfers the first main chain certificate into the third account to a plurality of first verifiers, and then receives digital signatures of the transaction from the terminal devices of the first verifiers respectively to form locking certificates (namely first certificate information); 3) the server 130 issues a first side chain credential corresponding to the value of the locked first main chain credential on the side chain 1311 according to the lock credential (i.e., the first credential information) to a second account of the user 101 on the side chain 1311; 4) the user 101 transfers the first side chain voucher stream issued by the server 130 in the second account to the sixth account of the user 102 in the side chain; 5) when the user 102 wants to convert the first side link pass certificate in the sixth account into the corresponding first main chain pass certificate, the user 102 transfers the first side link pass certificate in the sixth account into the fifth account for destruction; 6) the server 130 sends the transaction that the user 102 transfers the first side link in the sixth account into the fifth account to the plurality of second verifiers, and then receives digital signatures of the transaction from the terminal devices of the plurality of second verifiers respectively, so as to form a destruction proof (i.e. second proof information); 7) the server 130 unlocks according to the first main chain pass certificate, which is locked by the user 101 in the third account of the main chain 131 by the destruction certificate (i.e., the second certificate information), and corresponds to the first side chain pass certificate value, and sends the unlocked first main chain pass certificate to the fourth account of the user 102 in the main chain 131. By the mode, a mechanism of main chain evidence-passing locking, namely side chain evidence-passing issuing is formed, and the stability of a block chain system is further ensured.

Optionally, the operation of obtaining a second main chain pass certificate corresponding to the second side chain pass certificate from the third account includes: calling second certification information for transferring the second side link certificate into the fifth account; and acquiring a second main chain certificate from the third account according to the second certificate information.

Specifically, the user 101 needs to transfer the second side link voucher (e.g., the second side link voucher is used by the user 102 to trade with the user 101) in the account on the side link 1311 to a fifth account designated on the main chain 131, and the fifth account has a function of destroying all the side link vouchers transferred to the account. After the user 101 transfers the second side link certificates (e.g., 100 second side link certificates) to the fifth account, second certification information is generated to certify that the user 101 has transferred the 100 second side link certificates to the fifth account. The server 130 will obtain 100 second backbone passes that the user 102 originally transferred to the third account for locking, and then the server will issue 100 backbone passes to the account of the user 101 on the side chain 1311. In this way, the sum of the number of free main chain passes owned by the user 101 before the side chain passes are destroyed and the number of side chain passes is made equal to the number of main chain passes owned after the destruction. Therefore, a balance is achieved between the evidence-passing destruction and the evidence-passing distribution, and the stability of the transaction activity based on the block chain system is further guaranteed.

Optionally, the fifth account includes a plurality of second verifiers, and the second attestation information results from an operation of the plurality of second verifiers confirming that the fifth account received the second side-link attestation.

Specifically, the fifth account is supervised and managed jointly by a plurality of verifiers. For example: when the server 130 detects that the fifth account receives the side chain pass certificate transferred by the user 101, the server 130 sends the transferred transaction to the terminal devices of a plurality of verifiers respectively, and the plurality of verifiers verify the validity of the transferred transaction through digital signatures. When the server 130 receives the digital signatures of the verifiers, second certification information is generated for certifying that the transaction is officially existed and legal. By the method, before the server 130 issues the main chain voucher to the user 101, the proof that the side chain voucher is transferred to the fifth account by the user 101 is called, and then the main chain voucher is issued to the user 101 according to the proof, so that the issue of each main chain voucher is based on the evidence, and the stability of transaction activities based on the block chain system is further ensured.

According to the second aspect of the embodiment of the present invention, there is also provided a block chain-based evidence-passing processing method as shown in fig. 4. Fig. 4 is a flowchart of a block chain-based general evidence processing method according to the second aspect of embodiment 1 of the present invention. The method may operate on the server 1230 shown in FIG. 2 and, with reference to FIG. 4, the method includes:

s401: receiving a locking request for locking a first main chain certificate in a second account from the first terminal device, wherein the second account is an account of the first terminal device on the main chain;

s402: locking the first backbone certificate in response to the lock request;

s403: generating a first side chain permit on the side chain corresponding to the first main chain permit; and

s404: and sending the generated first side chain general certificate to a first account, wherein the first account is an account of the first terminal device on the side chain.

Specifically, for example and without limitation, the present application provides a lock request that may be received by server 130 from a first terminal device (e.g., terminal device 141 or terminal device 142 or terminal device 143 or terminal device 144) to lock a first backbone pass-through in a second account (i.e., an account of user 101 on blockchain backbone 131). Server 130 then locks the first backbone certificate in response to the lock request. The server 130 then generates a first side chain credential on the side chain corresponding to the first main chain credential. A first side chain proof is generated on the side chain 1311 based on the first proof information. Finally, server 130 sends the generated first side-chain pass-certificate to the first account (i.e., the account of user 101 on blockchain 1311).

Therefore, the application scenario of the

blockchain sidelines

1311, 1312, 1313 or 1314 is single, and the problem that the consensus mechanism of the sidelines in the transaction is emphasized does not exist, so that the requirement of users in different scenarios for performing transaction activities based on the blockchain can be met at the same time.

Example 2

According to a first aspect of the embodiments of the present invention, there is provided a blockchain-based evidence processing apparatus 600 for implementing the blockchain-based evidence processing method according to the first aspect of embodiment 1, as shown in fig. 6, the apparatus 600 includes: an issuing request receiving module 610, configured to receive, from a first terminal device, an issuing request for issuing a first sidelink passphrase to a first account, where the first sidelink passphrase is used for performing a transaction on a sideline, and the first account is an account of the first terminal device on the sideline; a first certification information obtaining module 620, configured to obtain first certification information in response to the issuance request, where the first certification information is used to certify that a first main chain credential corresponding to the first side chain credential is locked on the main chain; a first side link certificate generation module 630, configured to generate a first side link certificate on a side link according to the first certificate information; and a first side chain voucher sending module 640, configured to send the generated first side chain voucher to the first account.

In order to solve the technical problem, the present application provides a method for receiving an issuance request for issuing a first side chain voucher to a first account (i.e., an account of a user on a side chain of a blockchain) from a first terminal device through an issuance request receiving module 610. Then, the first certification information obtaining module 620 obtains, in response to the issuance request, the first certification information that proves that the user has locked his/her backbone credential in the account on the blockchain backbone. The first side chain credential generation module 630 then generates a first side chain credential on the side chain based on the first credential information. Finally, the first side link pass certificate sending module 640 sends the generated first side link pass certificate to the first account.

Therefore, the application scene of the block chain side chain is single, and the problem that the common recognition mechanism of the side chain in the aspect of transaction is emphasized is solved, so that the requirements of users in different scenes on transaction activities based on the block chain can be met simultaneously.

Therefore, in this way, the device 600 of the present disclosure transfers the transaction activities on the main chain between users in different application scenarios to the side chain, so that the transaction activities on the side chain have the characteristics of high speed and high security. Therefore, the transaction requirements among users in a plurality of application scenes can be met simultaneously. Further, the problem that the consensus mechanism on the main chain of the blockchain cannot simultaneously meet the requirements of users in multiple application scenes when transaction activities are carried out between two or more users in different application scenes due to different application scenes and different emphasis of the consensus mechanism in the conventional blockchain technology is solved.

Optionally, the first certification information is certification information of the first terminal device for transferring the first main chain general certificate to a third account specified on the main chain. For example: the user needs to transfer the main chain permit in the account on the main chain into a third account appointed on the main chain, and the third account has the function of locking all main chain permits transferred into the account. After the user transfers the backbone pass (e.g., 100 backbone passes) to the third account, the device 600 will issue 100 side passes to the user's account on the side chain. In this way, the number of free backbone passes that the user possesses before locking the backbone pass (i.e., the backbone pass that is not locked) is equal to the sum of the number of free backbone passes that the user possesses after locking and the number of side chain passes. Therefore, a balance is achieved between the certificate passing locking and the certificate passing issuing, and the stability of the transaction activity based on the block chain system is further guaranteed.

Specifically, the third account is commonly supervised and managed by a plurality of verifiers. For example: when the device 600 detects that the third account receives the main chain pass certificate transferred by the user, the device 600 sends the transferred transaction to the terminal devices of a plurality of verifiers respectively, and the plurality of verifiers verify the validity of the transferred transaction through digital signatures. When the device 600 receives the digital signatures of multiple verifiers, it generates a first authentication message for authenticating that the transaction is present and legitimate. By the mode, before the device 600 issues the side chain voucher to the user, the proof that the main chain voucher is transferred to the third account by the user is called, and then the side chain voucher is issued to the account of the user on the side chain according to the proof, so that the issue of each side chain voucher is based on the evidence, and the stability of the transaction activity based on the block chain system is further ensured.

Optionally, the method further comprises: the conversion request receiving module is used for receiving a conversion request for converting a second side chain pass certificate into a corresponding second main chain pass certificate from the first terminal equipment, wherein the second side chain pass certificate is a side chain pass certificate sent to the first account by a fourth account of the second terminal equipment on a side chain; the second side chain communication certificate transferring module is used for responding to the conversion request and transferring the second side chain communication certificate to a fifth account appointed on the side chain; the second main chain evidence obtaining module is used for obtaining a second main chain evidence corresponding to the second side chain evidence from a third account, wherein the second main chain evidence is the main chain evidence sent to the third account by a sixth account of the second terminal on the main chain; and the second main chain evidence obtaining module is used for obtaining a second main chain evidence obtained by the first main chain evidence obtaining module and obtaining a second main chain evidence obtained by the second main chain evidence obtaining module.

Specifically, when a first user of a first terminal device wants to convert a second side-chain pass (100 second side-chain passes) issued by the apparatus 600 to an account of the first user on a side chain, which is obtained when a transaction is performed with a second user of a second terminal device, into a main-chain pass, the first user sends a request for converting the 100 side-chain passes into 100 main-chain passes to the apparatus 600 through the first terminal device. The conversion request receiving module receives the conversion request, and then the second side-link certificate transfer module transfers 100 second side-link certificates owned by the first user to the specified fifth account in response to the conversion request. And then the second main chain license obtaining module obtains 100 main chain licenses, which are transferred to the third account by the second user through the second terminal device, from the third account. Finally, the second main chain evidence sending module sends the 100 main chain evidence to the first account of the first user on the main chain. In this way, when the first user wants to convert the side chain pass of the second user obtained through the transaction into the main chain pass of the first user, the device 600 unlocks the second main chain pass, which is originally transferred to the third account for locking, by transferring the side chain pass of the second user obtained by the first user to the fifth account, and sends the unlocked second main chain pass to the first account of the first user on the main chain.

Optionally, the second main-chain evidence obtaining module includes: the calling submodule is used for calling second certification information of the second side link certification transferred to the fifth account; and the obtaining submodule is used for obtaining a second main chain certificate from the third account according to the second certificate information.

Specifically, the first user needs to transfer a second side link permit in the account on the side chain (for example, the second user uses the second side link permit to trade with the first user) to a fifth account designated on the main chain, and the fifth account has a function of destroying all the side link permits transferred to the account. Second attestation information may be generated after the first user transfers second sidelink credentials (e.g., 100 second sidelink credentials) to the fifth account. The recall submodule then recalls second attestation information that attests that the first user has transferred the 100 second sidelink attestations into the fifth account. The obtaining sub-module then obtains the 100 second main-chain passes that the second user originally transferred to the third account for locking, and then the apparatus 600 issues 100 main-chain passes to the account of the first user on the side chain. In this way, the sum of the number of free main chain passes owned by the first user before the side chain passes are destroyed and the number of side chain passes is equal to the number of main chain passes owned after destruction. Therefore, a balance is achieved between the evidence-passing destruction and the evidence-passing distribution, and the stability of the transaction activity based on the block chain system is further guaranteed.

Specifically, the fifth account is supervised and managed jointly by a plurality of verifiers. For example: when the device 600 detects that the fifth account receives the side chain pass certificate transferred by the first user, the device 600 sends the transferred transaction to the terminal devices of a plurality of verifiers respectively, and the plurality of verifiers verify the legality of the transferred transaction through digital signatures. When the device 600 receives the digital signatures of multiple verifiers, it generates second verification information for verifying that the transaction is present and legitimate. In this way, before the device 600 issues the main chain voucher to the first user, the proof that the first user transfers the side chain voucher to the fifth account can be called, and then the main chain voucher is issued to the first user according to the proof, so that the issue of each main chain voucher is based on the evidence, and the stability of the transaction activity based on the block chain system is further ensured.

According to a second aspect of the embodiments of the present invention, there is provided a blockchain-based certification processing apparatus 700 for implementing the blockchain-based certification processing method according to the second aspect of embodiment 1, as shown in fig. 7, the apparatus 700 including: a locking request receiving module 710, configured to receive, from the first terminal device, a locking request for locking a first main chain credential in a second account, where the second account is an account of the first terminal device on the main chain; a locking module 720, configured to lock the first main chain credential in response to the locking request; a first side chain general evidence generating module 730, configured to generate a first side chain general evidence corresponding to the first main chain general evidence on the side chain; and a first side chain voucher sending module 740, configured to send the generated first side chain voucher to a first account, where the first account is an account of the first terminal device on the side chain.

Specifically, the present application provides a lock request that can be received from a first terminal device through the lock request receiving module 710 to lock a first backbone pass-certificate in a second account (i.e., an account of a first user on a blockchain backbone). The locking module 720 then locks the first backbone credential in response to the lock request. The first side chain credential generating module 730 then generates a first side chain credential on the side chain corresponding to the first main chain credential. Generating a first side chain proof on the side chain according to the first proof information. Finally, the first side link passport sending module 740 sends the generated first side link passport to the first account (i.e., the account of the first user on the blockchain side link).

Therefore, in this way, the device 700 of the present disclosure transfers the transaction activities on the main chain between users in different application scenarios to the side chain, so that the transaction activities on the side chain have the characteristics of high speed and high security. Therefore, the transaction requirements among users in a plurality of application scenes can be met simultaneously. Further, the problem that the consensus mechanism on the main chain of the blockchain cannot simultaneously meet the requirements of users in multiple application scenes when transaction activities are carried out between two or more users in different application scenes due to different application scenes and different emphasis of the consensus mechanism in the conventional blockchain technology is solved.

It should be noted here that the issuing request receiving module 610, the first certification information obtaining module 620, the first side link voucher generating module 630 and the first side link voucher sending module 640 correspond to steps S301 to S304 in the first aspect of embodiment 1; the locking request receiving module 710, the locking module 720, the first side link certificate generating module 730 and the first side link certificate sending module 740 correspond to steps S401 to S404 in the second aspect of embodiment 1; the modules are the same as the corresponding steps in the implementation examples and application scenarios, but are not limited to the disclosure of the first embodiment. It should be noted that the modules described above as part of the apparatus may be run in the computer terminal 10 provided in the first embodiment.
